How can I make round modular buildings in Unreal Engine 4?

I am making a Colosseum Asset pack for a university course and I could do with some help with figuring out how to make the exterior sections of the Colosseum able to be put together in unreal to create the shape of the exterior.

How do I get this shape in Unreal Engine 4 using only each individual piece?

are you asking how to create the arches or how to place them proceduarally? or are you asking how to group the assets and turn them into one mesh?

to make the arches you probably want to use a 3d modeling program outside of the engine.

to place the assets well theres a few different ways to do that and it becomes a bit involved.

Essentially what I would like to know is if I can place the arches proceduarally in Unreal as a similar shape to the image above as I used 3ds max to create one arch, copied that one arch over and over again, then used the bend tool to make it circular in the shape of the Colosseum because my goal at the end of this is to have made an asset pack of each individual exterior layer of the Colosseum and have it so that people can use it to create their own Colosseum and I was wondering if I could use a method similar to the one I used in 3ds max to create the Colosseum in unreal using the arches that I’ve made in order to show that the asset pack works

you may be able to accomplish that with a spline. i would guess that using a spline would be the easiest way to go as you can create meshs that will follow the curve of the spline. i imagine that is what the curve tool in max is like(i dont use max). below is a link to a tutorial on splines that should help.

Thanks for the help, I appreciate it
